As sprinting gains popularity, enhancing anaerobic capacity, neuromuscular function, and cognitive performance is crucial. This study evaluated the effects of Total Motion Release (TMR) caffeine on these functions in male sprinters to optimize strategies. In this randomized controlled trial, 56 were randomly assigned control, caffeine, TMR, or plus TMR groups. The Stroop test, Eriksen flanker task, FMS, Wingate test used pre- post-intervention, with analyzed via within- between-group...

Previous studies have shown that athletes recovering from anterior cruciate ligament (ACL) reconstruction experience a decline in motor cortex excitability and injury-related cortical reorganization, potentially leading to ongoing complications higher risk of subsequent injuries. Therefore, incorporating an intervention consistently delivers sensory inputs the central nervous system enhances at both spinal supra-spinal levels, addition exercise therapy, may offer greater benefits. The...

For a ring endomorphism α, we introduce and investigate skew Hurwitz serieswise Armendariz (or SHA) rings which are generalization of α-rigid determine the radicals series (HR, α), in terms those R. We prove that several properties transfer between R extensions, case is an SHA-ring. also construct various types nonreduced SHA-rings.

Despite the widespread use of whole-body vibration (WBV), especially in recent years, its neurophysiological mechanism is still unclear and it yet to be determined whether acute short-term WBV exposure produce neurogenic enhancement for agility.To compare effects on H-reflex-recruitment curve agility.Cross-over study.Clinical electrophysiology laboratory.20 nonathlete male volunteers (mean age 24.85 ± 3.03 y).Subjects were randomly divided into 2 groups, H-reflex agility. In sham protocol,...

We say that a *-ring R is generalized quasi-Baer if for any ideal I of R, the right annihilator In generated, as ideal, by projection, some positive integer n depending on I. A unital left primary and only with no nontrivial central projections. study basic properties such rings we prove their permanence Morita invariance. show this notion well-behaved respect to polynomial extensions certain triangular matrix group rings. sheaf representation *-rings also proved. obtain algebraic examples...

A bounded linear operator T on a complex separable Hilbert space H is called two-isometry, if <TEX>$T^{*2}T^2-2T^*T+1=0$</TEX>. In this paper it shown that every two-isometry not supercyclic. This generalizes result due to Ansari and Bourdon.

Abstract For a ring R and an endomorphism $$\alpha $$ <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML"> <mml:mi>α</mml:mi> </mml:math> of , we provide full description left right singular ideals the skew Hurwitz polynomial $$(hR,\alpha )$$ <mml:mrow> <mml:mo>(</mml:mo> <mml:mi>h</mml:mi> <mml:mi>R</mml:mi> <mml:mo>,</mml:mo> <mml:mo>)</mml:mo> </mml:mrow> . We obtain that if is automorphism then (resp., left) nonsingular only (hR,\alpha ) nonsingular. give example such nonsingular, but not

It is well known that when a ring R satisfies ACC on right annihilators of elements, then the singular ideal nil, in this case, we say nil-singular. Many classes rings whose ideals are but do not satisfy annihilators, presented and behavior them investigated with respect to various constructions, particular skew polynomial triangular matrix rings. The class nil-singular contains π-regular closed under direct sums. Examples provided explain delimit our results.

This paper is concerned with integrating of two classes trigonometric functions using line integration. The first class, also gives us a formula involving arc tangent functions.

Summary Wellbore instability can increase drilling time and sometimes leads to wells being side-tracked. Appropriate estimation of the weight mud be mentioned as key designing factor ensure mechanical stability wellbores. Considering elastoplastic behavior medium, yield criterion plays a role in this analysis estimation. Applying Mohr-Coulomb underestimation rock strength due ignoring effect intermediate principal stress. On other hand, Mogi-Coulomb is able consider stress, while preserves...

In this paper we provide new examples of Banach $ \ast $-subalgebras the matrix algebra $M_n(\mathscr{A}) over a commutative unital $C^*$-algebra $\mathscr{A}$. For any involutive algebra, define two involutions on triangular extensions. We prove that algebras are ${\ast}$-algebras and primitive ideals these some their all maximal.*******************************************************************************

Background: Parkour is a sport with alternating energy system in which some items such as lower body explosive power, muscular strength, production of high levels power the shortest period time and agility are particular importance.Considering anabolic anticatabolic properties beta-hydroxy beta-methyl butyrate (HMB), aim this study to investigate effect taking supplement along plyometric training on composition, standing jump parkour athletes. Materials Methods: For purpose, forty trained...
